Abstract

This paper presents the design of a protection scheme of a short 154-kV test line with a 154-kV superconducting fault current limiter (SFCL) in the Gochang Power Test Center of Korea Electric Power Corporation. The scheme includes a new protection algorithm proposed by Korea Electrotechnology Research Institute for protecting the SFCL system. The protection scheme is verified by protective coordination simulations on a Gochang power system using PSCAD/EMTDC program in this paper.
